Someone got ahold of Harry Potter and the Half-Blood Prince before it was supposed to be released to the public and scanned pages 596, 597, and 606 to prove that Snape killed Dumbledore. The pictures spread like wildfire and ruined many Harry Potter fan's lives.

1) A period of music ranging from the middle 1700s to the early 1800s. Famous classical composers include Beethoven, Mozart, and Haydn.

2) A bastardization of all "traditional" types of music (orchestral, choral, etc.). Derived from the classical period. Other periods include prehistoric, medieval, renaissance, baroque, romantic, 20th century, and 21st century.

The only classical music that most people have listened to is the ambient, therapeutically-designed background music at Barnes & Noble.
